Advice.

So long story short I don’t speak to my dad because of emotional abuse. For example, he’d call and if i dont answer he’d say how he’d kill himself if I wasn’t in his life. Or when I’d see him after awhile he’d comment on how my boobs have gotten bigger or butt. And he’s controlling, taking my phone and looking through it, stalking me when I’m driving and following me. So i had to cut him off because at that point he scares me and it’s toxic and emotionally draining. I’m 20. I’m due in 10 days and expecting my first and he somehow found my registry and bought something for my baby. Should I unblock him and tell him thank you? I am thankful, but I cannot have a relationship with him, he creeps me out telling me i remind him so much of my mom etc (he still loves her and they’re divorced). I dont want to seem ungrateful.
